Current-tunable chaotic jerk circuit based on only one unity-gain amplifier

A new current-tunable chaotic jerk circuit is proposed based on a single unity-gain amplifier. The circuit initially demonstrates a feasible use of a simple unity-gain amplifier for a chaotic jerk oscillator. Bifurcation is adjustable using a current source. Chaotic attractors are illustrated on an [X,Ẋ] plane and an [f₁(X,Ẋ,Ẍ), Ẋ] plane. The latter is revealed numerically and experimentally where f₁(X,Ẋ,Ẍ) is a simple algebraic sum of scaled X,Ẋ and Ẍ. A homoclinic orbit is included.
